BORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 499,027, dated June 6, 1893.

Application filed October 3, 1892. Serial No. 447,616- (No model.)

To all whom it may concern:

Be it known that I, BART LOBEE, a citizen of the United States, residing in Bufialo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Boring-Machines, of which the following is a specification.

My invention relates to certain improvements in machines for boring long distances through the ground or across a street or for other purposes, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in Which- Figure 1 is a side elevation showing the machine complete. Fig. 2 is an end elevation, looking in the direction of the arrow V, Fig. 1. Fig. 3 is an enlarged end elevation 'of a portion of the gear frame, showing the end of the screw bar and the means for engaging with or disengaging from the screw thread in' the screw bar.

The object of my invention is to provide a suitable and convenient means for boring a hole either in a horizontal direction through the ground or at any desired angle, whereby an opening may be made, for instance, across a street from cellar to cellar for receiving wa ter or gas pipe or for other like purposes, and thereby 'avoid the usual necessity under such circumstances, of tearing up a street pavement. This machine is also adapted for many other purposes for which a boring machine is required.

Referring to said drawings-the base, 1, may be of wood, but any suitable well known material maybe used. The base portion, 1 is preferably made of cast iron and is rigidly secured to the base, 1. It is provided with a central socket, 2, in which the vertical bar, 3, is rigidly fastened so as to act as a supporting standard for holding the operating parts of the device. On this bar, 3, is an adjustable split tubular clamping piece, 4:. It is adapted to be adjusted either up or down thereon, and is rigidly clamped in place by means of a set screw, 5, as will be readily understood by reference to Figs. 1 and 2. At the back of the clamping piece is another similar clamping piece, 6, (see Fig. 2) which is rigidly secured to it or formed in one piece with it. It is placed transversely or horizontally across the clamping piece, 4, and is clamped tightly by means of a set screw, 5 shown in Fig. 2. It is adapted to receive and hold the round bar, '7 (also shown in Fig. 2) which bar is rigidly fastened to or forms a part of the cross bar, 8, on the substantially A shaped gearing frame, 9. This gearing frame consists of the side frame pieces, 9, having the cross piece, 8, and the holding portions, 10, through which the screw bar, 11, passes.

Mounted vertically in bearings in the apex and crosspiece of the gearing frame so as to turn therein, is a vertical shaft, 12. This construction of the frame and the bar makes a very strong, compact and convenient device.

At the bottom of the shaft, 12, is rigidly secured a bevel wheel, 9 and at the top is a removable hand wheel 14, substantially as shown in Fig. 2, or a handle, 14, as shown in Fig. 1.

.Either will answer the purpose but for some purposes the hand wheel would be preferable both are made removable by means of a screw portion, 15, on the screw bar, shown in Figs. 1 and 8.

16 represents a bevel gear wheel having a central hole through which the screw bar 11, can slide easily back and forth. In the screw bar is a longitudinal groove 17, and in the gear wheel, 16, is a well known key which while it prevents it from turning on the screw bar, 11, it allows said bar to be moved back and forth through it as above mentioned. This gear wheel, 16, gears in with the wheel, 9 so that when one turns the other turns.

At the front of the screw bar, 11, is a screw portion similar to the screw portion, 15, at the opposite end of said bar on which is secured an extension piece, 18, see Fig. 1, adapted to receive the screw end of a piece of gas pipe, 19, (see Fig. 1.) To the opposite end of the pipe, 19, is secured by means of the well known screw portion an anger, 20, and on the pipe, 19, is placed a loose collar 21, which is made the same size or slightly smaller than the hole which the auger bores. Its object is to keep the pipe, 19, central in the hole as the auger passes forward.

From the above described constrpction it will be seen that as many intermediate pipes, 19, may be connected together to carry the auger to any distance required, and that by loosening the clamping screws 5 and 5 the auger may be set at any angle required, and after the screws 5 and 5, are tightened the parts will be held at the angle it is desired to bore the hole. The anger is operated by turning the handle or hand wheel, 14!, or 14, but it may be operated by transferring the hand wheel, 14, from the vertical shaft 12, to the end 15, of the screw-bar, 11, and the augeroperated direct by said hand-wheel.

To cause the screw bar to be fed forward while boring I employ a pivoted plate, 22, secured by a pin, 23, to the gearing frame. It is brought into engagement with the screw thread in the screw bar by turning it down as shown, and is disengaged from it by turning up as shown by the dotted lines, 24, in Fig. 3.

I claim as my invention In a boring machine, the combination, with a supporting standard, of a clamping piece ad justably secured thereto, a substantially A shaped gearing frame, the apex and cross piece of which are each provided with a bearing, and the side pieces are each provided with a bearing, a laterally projecting bar rigidly secu red to the cross piece of the frame and adj ustably secured to the clamping piece, a screw shaft in the bearings of the side pieces of the frame, one end of which shaftis adapted to be provided with a boring tool, a bevel Wheel on the shaft between the side pieces, an operating shaft in the bearings in the apex and cross pieces of the frame, the end of which shaft within the frame is provided with a bevel wheel, a plate pivotally secured to one of the side pieces of the frame, and means for operating the device, substantially as set forth.

BART LOBEE.
